SU33001A1 - Logging method logs in rafts - Google Patents

Description

Techniques for viscous logs afloat by means of a floating device that binds logs with a wire is generally known. In the proposed method, each log, captured by a suitable floating device, is fed to linking with other logs under the device, under the weight of which all coupling logs are aligned to prevent the raft from distorting.

The floating device used for the proposed method, a part of which is depicted in fig. 1 of the drawing in the form of a sbsk and flg. The 2-top view acts like a loom during a tie.

Across the assembled logs, two main bars 24 are laid near their cabins, constituting together with the cross bar connecting them 16 the device frame. On the brackets 21 at the ends of the beam / is installed in the twitching mechanism, consisting of two figured to lengular levers 7 -4 and 2-5, pivoting on the shaft 5 lying in the brackets 21, and the lever 7-4 to her long sleeve 25

64S

the bridge is free on the shaft, and the lever 2-5 is rigidly fixed on it. Both levers, by means of rods 5 and P and connecting rods o and 7, are rotated by some engine mounted on the device itself or on shore. The shoulders 7 and 2 of these levers, when swinging, straighten the logs either from above, then with two wires 7 7 from the coil (left on the drawing) along hub 25 and missing ears or frame on the xsl, ah shoulders 7, 2 levers. Wires for providing constant tension are provided on the way from the reel and on the blocks with weights 10.

For the supply of logs to the device, there are clamps 77 and 18, made in the form of pivoting levers with hooks at one cm and with short wheels 22 - on the other. The grippers can rotate on axles 26, moving along the device along the guides not shown in the drawing, and move forward and backward in the direction transverse to the equals, being the ends of their short elbows 22 through the connecting rod. Ju 72 and 75 articulated .1Y with rods 7 and 14 receive

the reciprocating is moved in parallel to 3 with rods (5 and P from the same bit: -: tatel. Thus, when moving and stock and 3 and / 4 forward to the stop: well, incoming units / P, 20 provide vazts first, with using the short bend 22, lifting the hook of one or another grip 77 or J8 and then advancing it along the way, and when the rods 75 and J4 are retracted, the hook of the grip hook is lowered down the shaft / 9, attaching the latter under the bar 24 devices and pressing the log 19 to the logs previously let down 23. The supply of each new log occurs when shoulders are 7 and 2 colas j-4 and 2-5 knobs levers, in a manner like a throat into which a captured and pullable log passes freely. By pressing it to a row of loose logs, the shoulders 7 and 2 from the reverse movement of the rod and P close the indicated throat, covering new log wire 77 and TJ: M linkage

23 rafts with the rest of the logs. Thus, wb, each course of levers 7 and 2 binds one log. Since this link occurs when the bridge is already under the main bars 24, it is natural that all the logs are aligned with the height of the device, and the raft is protected from distortion during the tie.

The subject matter of the invention.

The way the logs are viscous into rafts by the way of Davis is afloat with a p .: power of a floating device that binds a wire, characterized in that each log is covered by a wire loop under the device used to bind them, in order to level off the raft and the safety of the latter, under the action of the weight of the said device, from crushing during the viscous period.
